Small technical issue I encountered: in Vivaldi, “right click + left click” is used as a shortcut for going to the previous page. To be honest I didn’t know that until today! :p Also, some balls can be hard to see for colorblind. I had struggles with the green one, and surprisingly a small brown/blue one.
But those tiny disagreements aside, the game is really fun! The physics feels great and juicy, and it’s actually satisfying to clear the board! The fact that most items and perks have visible effects make them fun to discover. It’s a good thing you put a message at the end, because I’d be definitely be playing this for an entire hour without it! x) Congrats for making this cool entry.
